Why would an experienced pilot want a “Low Thrust Detector” on his twin? For the
same reason that Gene
Cernan ( an experienced
navy pilot and Apollo astronaut ) put a LTDS system on his Cessna 421. Enclosed
are some customer comments: Michael
Baker
(Cessna 421 C) “We
credit the low Thrust Detector System with providing us with a timely,
recognizable and unmistakable signal that we had an engine problem in a
critical flight condition. Without
a doubt this warning gave us an edge that facilitated our ability to
make an informed and immediate decision in what may have been an
extremely critical situation.” Paul
G. Jacops (Cessna
414) “power loss was not immediately felt. The "incipient engine failure light", on the Low Trust Detector System gave the first clue” “I attribute the safe conclusion of the flight to the early detection by your system” “Early notice and action is the key.” Robert
F. Jasse (Piper
Seneca) “The
diaphragm in the fuel pump had ruptured,
a failure, which simply could not have been predicted. The plane is very
well maintained, the Robertson Conversion works perfectly and I have had
good training, but I must say that the
immediate confirmation of right engine failure by your zero thrust
indicator probably saved my ass.” Gino
C. Guido, (Beech
Baron B55) “Right after rotation, “sure enough", it happened. The left light indicator started blinking, the left yellow light on the RPM lever started blinking and the horn was very much audible. of course I aborted the take‑off right there” “Nothing else but a plugged up fuel injector nozzle. Not a tragedy, but logically by continuing the take‑off could very well have been a very expensive replacement of a cylinder barrel or whatever.” “Therefore. Mr. Hall, please know that I am very very pleased and I will recommend the L.T.D.S to all twin pilots I know.” John A. Van
(Beech Baron 58P) “the installation
was one in which the
LTDS paid for itself many times over.”
“The quick notification of the LTDS turned a potential disaster
into a minor incident. The cause of the problem was a simple 90 cent
pressure clamp.” Robert
F. Griffith. (Piper PA31/325 CR Navajo) It is my professional opinion that all multi‑engine aircraft should be equipped with a Low Thrust Detector system, regardless of pilot experience. John M. Miller
(Beech Baron 56TC) ”The lives it may save may be their own, and a few others besides.” A
classic engine out on
takeoff can be handled, but the following ?? Your on
instruments, in
turbulence and turning to a heading, just after takeoff, and an engine
fails! Partial
power loss during
takeoff roll that may lead to a total failure. A
surging engine during
a complicated approach. Your
twin will yaw in both directions and continue to oscillate with power
that is cutting in and out. Our
LTDS tells you instantly which engine is causing the problem! Partial
power loss when the
autopilot is engaged. The autopilot
can counter some yaw, you may not notice a problem.
Your LTDS will give a pulsing tone and lights that will get your
attention. The average engine out climb angle for piston twins is only one and one half degrees at best rate of climb and only after the prop is feathered and the aircraft is cleaned up. Draw a 1 1/2 degree angle on paper. Very shallow! Six
seconds wasted will put you in the trees or off the end of the runway. All
piston twins have a negative climb
rate with a wind-milling prop. A
power failure is worse than just pulling the throttle back to simulate
an engine failure. You are
still generating some power with an idle power setting.
An actual engine failure creates more drag from the wind-milling
prop and more drag on the engine-out side.
An engine failure may create a higher VMC than FAA flight
tests, which only require retarding the throttle.
As a test pilot (and with the FAA aboard) I ended up inverted and
doing a split S to recover. ( over 1000 feet lost ) ( Cessna 414A flight testing ) Yes
! We
have had customers that have had an engine failure
with our LTDS system installed. Click

Low Thrust Detector System Identifies
the prop control of the failed engine instantly! Warns
of partial power loss, on takeoff or approach! Works
in turbulent air, when the slip skid ball may just be bouncing. Works
on the initial ground roll, when tire friction may not allow yaw. You
still make the decision to feather, but with a positive
identification. Prevents the deadly mistake of feathering the wrong propeller. |

Can
you afford a “Low Thrust Detector” on your twin? I
have dealers who install the system to increase the marketability and
value of an aircraft. The
value added to the aircraft is more than the cost. What
is the value of avoiding a potential accident.
Can you put any value on the persons that fly with you. Flying is as safe as you make it, how many individuals did you know in aviation, that are not here today. The price for not having this system could be enormous. |
